Planetary gears

Planetary Gear cut away

Framo Morat planetary drives provide you with all the freedoms and options, because we can offer the right solution for any application, no matter how specialized it is. Based on the preconfigured and quickly available PL & PS series planetary drives, our modular system provides you with numerous variants to configure the drive according to your requirements. For drive solutions tailored completely to your individual specifications, you benefit from our expertise in development and systems, which has been growing for decades. This allows us to provide you with the best possible variant for any application.

Custom Planetary Gears

Benefits at a glance:

  • Individual choice of material, Diameter, mounting, tooth width, etc. for each planetary stage
  • Perfect linkage at every interface
  • Integration of the drive in your complete system, taking into account mechanics, electronics and control technology

“Your idea – Our drive”: Following this philosophy, we set standards with drive solutions for various applications and industries. Our customers value us as an experienced development partner, who supplies a product that is appealing both in terms of technology and cost-efficiency.

Many innovative special systems with a planetary drive as its core element have already been developed in this way – one example is the drive for tracking mirror reflectors, which was developed by Framo Morat. The highest requirements for circumferential backlash and torque were of paramount importance in this development. The drive consists of a servomotor, a 3-stage planetary drive, a worm gear, a position tracking system and two adapter plates. Overall, one drive can move 330 m² of mirror. A special feature of this development is the size adjustment of the various planetary drive stages. The planetary drive achieves a gear ratio of 729:1. You can find additional examples here…

This wealth of experience benefits you. You benefit from our system expertise that we have acquired through the technical implementation of numerous drive solutions.

PS & PL series planetary drives

We have used our decades of experience in designing drives and complete drive systems to preconfigure the most common planetary drive variants for you. The result is the PL and PS series, which feature quick availability, economical design and the “Made in Germany” quality seal that Framo Morat is known for. Furthermore, our modular system provides you with a great number of variants so you can adapt your transmission accurately to your application. In practice, our planetary drives reliably provide power in automation technology, mechanical engineering or the packaging industry. You can find additional application examples here…
